WILLIAM SOBEY, OF RACINE, WISCONSIN, ASSIGNOR TO THE J. I. CASE PLOW\VORKS, OF SAME PLACE.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 389,860, datedSeptember 18, 1888.

Original application filed January 3, 1888, Serial No. 259,557. Dividedand this application filed March 31. 1888. Serial No.

To all whom it may concern..-

Be it known that I, WILLIAM SoBnY, a citizen of the United States,residing at Racine, in the county of Racine and State of \Viseonsin,

haveinvented certain new and useful Improvements in Cultivators,- and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it ap- IO pertains to make and use the same.

My invention relates to wheel-Cultivators, and provides a constructionwhich will assist in raising the plows and which will sustain them whenraised as long as may be desired.

[5 The peculiarities of construction and combination which constitute myinvention are illus trated in the accompanying drawings, and saidinvention is fully disclosed in the following specification and claims.

In the drawings,Figure 1 is asection through a wheel-harrow, showing mylifting device in elevation. Figs. 2, 3, 4, 5, 6, 7,8, and 9 are detailviews of parts of the machine.

In the constructions usually employed to lift the plows of cultivatorsand similar machines the lifting devices are attached in such a mannerto the main frame of the machine that when the plow-beams are moved toeither side of the line of draft they become out of alignment with thesaid lifting devices and the lifting force cannot be directly applied. Iobviate this difficulty by providing a construction of lifting devicewhich is always in line with the plows and so always exerts its force 35 directly, no matter how much the plow-beams are moved laterally. Thisforms an important feature of my invention.

In the drawings, the axle B is provided with a clamp, l), constructedand secured to the axle, as shown in Fig. 3, and provided with ears dand d at the front and rear of the axle for the passage of bolts. To theears d is pivoted the angular or L-shaped frame or standard G. (Shown indetail, Fig. 2.) This frame or standard is provided with the ear 9", anda perforation, g, in its lower arm for the passage of the bolt whichpivots it to the clamp D. The lower extremity of this angular standardis provided with a hook, g and its upper end 0 is formed with a slot, g.Near the central portion of this frame or standard is an aperareattached to these beams in precisely the same manner as is described inmy application for Letters Patent, Serial No. 259,557, filed January 3,1888, and by the use of these hinges and parallel beams a direct forwardmotion of the plows is secured.

In the slot 9 of the angular frame or standard is inserted a bolt, K, orsimilar device, which carriesa bell crank lever, J. This bolt may beformed, as shown in Fig. 4, in any other desired way, and connectsthebell-crank lever firmly to the standard, but permits it to turn upon thebolt as a pivot. A spring, H, connects the forward end of the lever Jwith the hook of the angular frame or standard, and the other end of thebell-crank lever is connected to the hookfon one of the parallelplow-beams E by means of a link or chain, j. The adjustment of thetension of the spring H is accomplished by adjusting the bolt to whichthe bell-crank lever is attached at different points in the slot of theangular frame or standard. The operation of raising the plows andsustaining them in position is identical with the operation described inmy application 8 5 before referred to. By this means the lifting devicesare always held in line with the plowbeams and move with them, so thatthe force of the spring in raising the plows is always directly applied.

In Figs. 5 and 6 I have shown two methods by which I may change theleverage of the bell-crank lever on either side to effect the adjustmentof the spring II or the linkj in relation to each other. I provide oneor both arms of the lever J with apertures j", as shown in Figs. 5 and6, or with notches i as shown in Fig. 6, by means of which the force ofthe spring may be regulated as the spring becomes weakened by use andallowance be made for [O0 heavier or lighter plows.

In Figs. 7, 8, and 9 I have shown means for regulating the tension ofthe spring H by raising or lowering the bell-crank lever upon itssupportingstandard. I may provide the bolt passing through the lever Jand standard with a portion having corrugations meshing withcorrugations on the standard, the said standard being provided withaslot to permit of raising or lowering the bolt; or I may form thestandard of two parts, each provided with corrugations, one of saidparts being also provided with a slot, by which means the same verticaladjustment may be secured without removing the bolt which carries thebell-crank lover.

I may use one clamp or hinge, D, for each plow-beam, or I may attach thetwo hinges to one clamp, as found most desirable.

I have shown my invention in connection with a twowheeled cultivator;but it may be applied to a sulky-plow or any other like machine having'vertieally-moving beams, plows, shovels, or teeth which it is desirableto raise and sustain in an elevated position.

I do not limit myselfto the exact construe tions herein shown anddescribed, as many modifications of the same may be made withoutdeparting from the spirit of my invention.

\Vhat I claim, and desire to secure by Letters Patent, is-

1. The combination, with a beam or dragbar, of an axle, a framepivotally connected with said axle, and a lever mounted on said frame,connected with said beam or drag-bar by an unyielding connection andconnected to said frame by an elastic connection, substan tially asdescribed.

2. The combination, with a beam or dragbar, of an axle, a frame having avertical part pivotally connected with the axle, a lever mounted on thevertical part of said frame, an unyielding connection between the leverand the beam or dragbar, and an elastic connection between the lever andthe frame, substantiall y as described.

3. The combination, with a beam or dragbar, of an axle, an L-shapedframe pivoted to said axle by a vertical pivot, a bell-crank leveradjustably mounted on the vertical arm of said frame, an unyieldingconnection between one arm of said lever and the beam or dragbar, and anelastic connection between the other arm and the horizontal arm of saidframe, substantially as described.

4. The combination, with a beam or dragbar, of an axle, a frame pivotedto the axle by a vertical pivot, a bell-crank lever mounted on saidframe, an unyielding connection between one arm of said lever and thebeam or drag'bar, and an elastic connection between the other arm of thelever and the frame, said connections being adjustable upon the lever,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

W'ILLIAM SOBEY.
